Study of the Reaction pi- p --> K0 Y* at 8.0-GeV/c, 10.7-GeV/c, and 15.7-GeV/c

Phys.Rev.D 15 (1977) 609, 1977.
Inspire Record 4145 DOI 10.17182/hepdata.24625

We present differential and total cross sections for the reactions π−p→K0[Σ(1385)Λ(1405)] and π−p→K0Λ(1520) at incident pion momenta of 8.0, 10.7, and 15.7 GeV/c. Pions from the decay of the forward K0s's were detected in the forward leg of the BNL double-vee spectrometer and the recoil Y* 's were identified by the missing-mass technique.

High Statistics Investigation of K0 K- Decay of a2- Produced by 23-GeV/c pi- on Hydrogen

Margulies, M. ; Kramer, M.A. ; Foley, K.J. ; et al.
Phys.Rev.D 14 (1976) 667, 1976.
Inspire Record 3806 DOI 10.17182/hepdata.24780

We present the results of an experiment to study the reaction π−p→A2−p, A2−→KS0K− at 22.4 and 23.9 GeV/c. We have 3346 KS0K− events in the effective mass region 1.1 to 1.5 GeV, and covering the |t′| interval 0.0 to 1.0 (GeV/c)2. Because of the low background in this channel, we are able to study various |t′| regions, including the region 0.2 to 0.29 (GeV/c)2 in which the original split A2 peak was observed. We find no substructure in any region. We have also derived differential and total cross sections. The differential cross sections are well fitted by the form dσdt′=At′ebt′ with b≈7.0 (GeV/c)−2. The total cross section is in good agreement with the value derived from other experiments that measure the A2−→ρ0π− decay mode.

Neutral associated production by 8, 10.7 and 15.7 gev/c pi- incident on protons

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.
Phys.Rev.D 8 (1973) 27-38, 1973.
Inspire Record 81979 DOI 10.17182/hepdata.22059

We present differential and total cross sections for two reactions: π−p→K0Λ and π−p→K0Σ0. The incident pion momenta were 8, 10.7, and 15.7 GeVc. The results are based on an analysis of approximately 22 600 events of the two reactions where the π+ and π− from the decay of the KS0 were detected in the forward leg of the Double Vee Magnetic Spectrometer. The separation of Λ recoils from Σ0 recoils was accomplished by the missing-mass technique.

K0(s) k- decay of a2- produced by 20.3-gev/c pi- on hydrogen

Foley, K.J. ; Love, W.A. ; Ozaki, S. ; et al.
Phys.Rev.D 6 (1972) 747-756, 1972.
Inspire Record 73969 DOI 10.17182/hepdata.22252

We present the results of an analysis of data for the reaction π−p→KS0K−p at 20.3-GeV/c incident π momentum. We find that the K0K− effective-mass spectrum shows a single peak in the A2 region which is well fitted by a Breit-Wigner shape. The data in the A2-peak region are inconsistent with the split-A2 shape reported earlier. The distribution in t of the A2 events shows a forward dip followed by an exponential falloff. The A2 decay angular distribution is well fitted by a single resonance with quantum numbers JP=2+. The results of an analysis of the density-matrix elements for this reaction are given.

Increased Statistics and Observation of the $g(T$), $g(T$)-prime, and $g(T$)-prime-prime 2++ Resonances in the Glueball Enhanced Channel $\pi^- p \to \phi \phi n$

Etkin, A. ; Foley, K.J. ; Hackenburg, R.W. ; et al.
Phys.Lett.B 201 (1988) 568-572, 1988.
Inspire Record 253944 DOI 10.17182/hepdata.30006

In a new experiment we have obtained 3006 new events in the reaction π − p → φφ n, approximately doubling the statistics which now total 6658. A refined partial wave analysis of the φφ system again reveals three resonances (g T , g T′ , g T′' ) with I G J PC =0 + 2 ++ . The absence of the OZI suppression, and the observation of only three J PC =2 ++ states (g T , g T′ , g T′' ) which comprise virtually all the cross section are unusual characteristics of the data. The large φφn signal occurs over a mostly structureless and incoherent φK + K − n background. All these unusual characteristics are well explained if these states are produced by 1–3 glueballs (multigluon resonances).

Study of k+ p ---> k0 delta++(1236), k- p ---> anti-k0 n, and k- p ---> anti-k0 delta0(1236)

Phys.Rev.D 9 (1974) 42-48, 1974.
Inspire Record 93128 DOI 10.17182/hepdata.21955

We have studied the reactions K+p→K0Δ++(1236) at 15.7 GeVc, K−p→K¯0n at 10.7 and 15.7 GeVc, and K−p→K¯0Δ0(1236) at 15.7 GeVc in the BNL Double Vee Magnetic Spectrometer. The π+ and π− from the decays of forward K0's were detected and the above reactions were identified by a missing-mass technique. Total and differential cross sections are presented for the first two reactions and a total cross section for the third.

MEASUREMENT OF J / psi PRODUCTION IN 280-GeV/c mu+ IRON INTERACTIONS

The European Muon collaboration Aubert, J.J. ; Bassompierre, G. ; Becks, K.H. ; et al.
Phys.Lett.B 89 (1980) 267-270, 1980.
Inspire Record 143938 DOI 10.17182/hepdata.27264

Virtual photoproduction of J/ ψ mesons has been measured for 280 GeV muon iron interactions in an iron/scintillator calorimeter target. The J/ψ's were identified by their decay into muon pairs. 315 events were observed, about half of which were elastic. The t , Q 2 and v distributions of these elastic events are presented. The v dependence is measured between 40 and 180 Mev and compared with lower energy photoproduction results. The Q 2 dependence is compared with the predictions of the vector dominance model.
